Rear cradle for supporting e.g. electrical motor of electric car, has side units integrated with part of cooling circuit, where circuit carries out coolant circulation to regulate temperature of electric components of traction chain of car

摘要

The cradle has side units (24) integrated with a part of a cooling circuit comprising a first exchanger between liquid coolant and air outside a car, where the cradle receives the circuit part, and the circuit carries out liquid coolant circulation to thermally regulate temperature of electric components of an electric traction chain of the car. A second heat exchanger performs heat exchange among the coolant and electronic parts e.g. inverter and/or battery charger, of the chain. Liquid coolant circulation conduits of the side units are connected with the second exchanger. An independent claim is also included for an electric car rear arrangement.
